Predictive Geodemographics

 

Geodemographic classifications are temporally static, but geodemographics are area-based classifications, and areas are dynamic.

 

\[ Geodemographic Change = ∑Sociodemographic Processes\]

Use multitemporal open data as proxies for attributes to sociodemographic processes (gentrification and displacement) to predict geodemographic change pairs.

 

 

Comparison of Methods

  • Gradient Boosting Machine
  • Multitemporal feature selecred variables - 51% accurate
  • Change Vector Analysis (CVA) - 48% accurate BUT greater speficity of dynamic geodemographic change

 

Visualisation

Introduced to new software - QGIS - to develop data visualisation skills, specifically for spatiotemporal data (with TimeManager plugin).

 

Mapping golden rules

  1. Black Background!

 

  1. Fancy Font?

  2. Existing colour packages, BUT experiment with blending modes

  3. Gifs - great for the lazy reader!

  4. QGIS TimeManager - perfect for quick, easy, effective GIFs, but also for the initial exploration and the visualisation of spatiotemporal data

  • Can I see any patterns?
  • Are they what I expected?
  1. Although I am working with spatiotemoral data, I may not always be able to display my outputs in the most appropriate manner (GIFs?!), but static maps can still be effective when using appropriate colours and blending

 

Reproducibility

How to better improve the reproducibility of your work via version control (Git)

 

My current folder organisation:

  1. Logical? X
  2. Easy to navigate? X
  3. A million seperate folders and document revisions? ✓

Version control is my friend

  1. Need to rerun a specific analysis? ✓
  2. Reproducible papers? ✓
  3. R? cmd? ✓
  4. Online collaborators? ✓

Science Communication

How to improve our communication (writing and presenting) through a series of small exercises to improve our writing process.

 

The purpose of scientific writing is to fill a gap in knowledge, and to tell and sell that knowledge with and the scientific community.
